.VF file not being generated

I am using ISE14.7 for a Spartan3-AN device and migrating from a Coolrunner device. Made a new project and made the additions I needed. The Top Level does not generate a *.VF file according to the synthesis report, looked and it does not have one. Double checked the old project files and the *.VF file is there. Any ideas or suggestions?

Re: .VF file not being generated

Hello @fhknapp44

 

1. Are you targeting coolrunner device while creating new project?

2. If not, target the coolrunner device and generate .vf files from the schematics.

3. Then use the generated .vf files and create a new project targeting Spartan-3AN device.

 

Try above steps and see if it helps.

 

Thanks,

Vinay

Re: .VF file not being generated

Vuppala: I have already made a new project and used the copy files function to bring all the schematics in and everything seems to work now. That impossible error message doesn't cause problems anymore. At least it gets trough synthesis without impossible error messages. I hope it get through the rest of the steps after I complete the changes.
